BELLCRANK 5V8291 - Caterpillar

Data Link Features
CAT Data Link Flash
Flash - This procedure is a method of downloading or programming electronic information.The CAT Data Link Flash provides the capability to flash the software that controls the engine by using the CAT Data Link. CAT Secondary Data Link
The CAT Secondary Data Link provides the ability for each ECM to have a CAT Data Link that is local to that engine. This feature also enables a global CAT Data Link to connect to other engine controls through a common data link. This data link enables the operator to communicate through a single Customer Communication Module (CCM) or through a telephone line with all of the engines that are in an engine room.The CAT Secondary Data Link provides the capability for as many as eight generator set engines to communicate via a remote display or a control panel. The CAT Secondary Data Link is for use with the following systems: switchgear, remote monitoring and control systems.Switching between data links requires the use of the Cat ET software. Refer to Systems Operation, Troubleshooting, Testing and Adjusting, RENR7902, "Electronic Modular Control Panel 3 (EMCP 3)" for more information.Air Shutoff
Note: Air shutoff is an optional feature.The air shutoff uses a plate that rotates on a shaft in order to shut off inlet air to the intakes. The engine stops because of the restricted air supply to the combustion chamber. The air shutoff only actuates for the following conditions:
The Emergency Stop button is pressed.
An overspeed shutdown occurs.
The jacket water coolant reaches the trip temperature.Cold Cylinder Cutout
Note: Cold cylinder cutout is an optional feature.The Cold Cylinder Cutout strategy is used so that the ECM may perform the following functions:
Reduce the white smoke for cold starting.
Minimize the duration of advanced timing (cold mode).
Reduce the use of ether injection.The ECM automatically turns off one electronic unit injector at a time during the following occurrences:
Cold start-up
Extended time at low idleThe ECM monitors the change of the fuel rack in order to determine if a cylinder is firing. If the cylinder is firing, the ECM activates the electronic unit injector. If the cylinder is not firing, the electronic unit injector remains deactivated. This condition reduces white smoke.The following conditions must be met in order to activate the Cold Cylinder Cutout strategy:
The Cold Cylinder Cutout parameter is programmed to "ENABLE".
The engine rpm is equal to high idle rpm or less than high idle rpm.
The fuel rack is less than 13 mm (.5 inch).
The jacket water coolant temperature is less than 63 °C (145 °F).The Cold Cylinder Cutout strategy is activated under either of the following conditions:
10 seconds after the engine reaches the low idle rpm
3 seconds after ether injection is completedThe following conditions will deactivate the Cold Cylinder Cutout strategy:
The Cold Cylinder Cutout parameter is programmed to "DISABLED".
The jacket water coolant temperature is more than 70 °C (158 °F).
The ET service tool is used for the cold cylinder cutout test.
The ether injection system is used.
The coolant temperature sensor has failed.
If the engine speed varies more
